ReqRes

ReqRes (reqres.in) is a hosted REST API originally launched by Ben Howdle as a free no-auth fake-API surface for AJAX prototyping, tutorials, and frontend testing. As of the 2025 relaunch it operates as a freemium SaaS product: every request to /api/* and /app/* now requires an x-api-key header obtained via free signup at app.reqres.in, while the /agent/v1/* Agent Sandbox is open in v1 with IP-based rate limiting. The legacy demo surface (/api/users, /api/login, /api/register, /api/unknown, delayed responses) continues to return the same fixture payloads it always has — what changed is the API-key gate and the addition of persistent collections, app users, custom endpoints, and an agent-targeted sandbox with deliberate failure scenarios. ReqRes remains the default fake-API endpoint cited in countless React, Vue, Angular, and bootcamp tutorials.

ReqRes publishes 6 APIs on the APIs.io network, including Agent Sandbox API, App Users API, Authentication API, and 3 more. Tagged areas include Development, Testing, Prototyping, Fake API, and REST.

The ReqRes catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

ReqRes’ developer surface includes authentication, getting-started guide, documentation, signup flow, pricing, engineering blog, and 13 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/reqres: open an issue to ask a question, or submit a pull request to add artifacts.

Notable capabilities this provider offers.

Legacy Demo Fixtures

Stable /api/users, /api/users/{id}, /api/unknown, /api/unknown/{id} fixture data preserved from the original reqres.in launch — the same payloads tutorials have been wired again...

Simulated Auth Flows

/api/register, /api/login, and /api/logout return success-shaped tokens without creating real accounts — drop-in for teaching auth patterns without standing up a real identity p...

Persistent Collections

/api/collections/{slug}/records supports GET/POST/PUT/DELETE with real persistence on paid plans, with custom schemas on the Dev tier and above.

Project-Scoped App Users

/app/* surface lets each app user authenticate independently with a session bearer, so client-side prototypes can model real per-user isolation.

Custom Endpoints

/api/custom/{path} executes user-defined endpoints, letting builders shape arbitrary REST surfaces without writing backend code.

Agent Sandbox

/agent/v1/* exposes endpoints designed for AI coding agents — cursor pagination, deeply nested resources, deliberate failure scenarios, and deterministic seeded fixtures.

15 Deliberate Failure Scenarios

The Agent Developer plan unlocks 15 failure scenarios on /agent/v1/scenarios so AI agents can be tested against timeouts, rate limits, validation errors, and pagination edge cases.

Delayed Responses

Legacy endpoints accept a ?delay=N query param to simulate slow upstream conditions — useful for spinner/loading-state testing.

HTTPS Only

Served exclusively over HTTPS at reqres.in.

CORS Enabled

All origins are allowed, making ReqRes safe to call directly from browser-based prototypes.

Use Cases 7

What developers build with this provider.

Frontend Tutorial Endpoints

The default fake API cited in React, Vue, Angular, and Svelte tutorials when an author needs a real HTTP endpoint without standing up a backend.

Bootcamp Curriculum

Coding bootcamps wire exercises against ReqRes legacy endpoints so students can practice CRUD flows on a stable, free, no-signup surface.

API Client Test Suites

Use the legacy and Collections surfaces to exercise HTTP client libraries (fetch, axios, requests, OkHttp) against a real REST API.

Frontend-First Prototyping

Build a UI against persistent ReqRes collections before standing up a real backend; swap in a real API later by renaming the base URL.

AI Agent Testing

Test AI coding agents against the /agent/v1/* sandbox — cursor pagination, deliberate failures, deterministic seeded fixtures.

Sales Demos

Power live sales demos for tools that need to talk to an API without exposing customer data.

Workshop Sandboxes

Hands-on workshops where every participant needs a working API endpoint in under a minute.

Scroll for all 7

Integrations 5

Pre-built integrations with other platforms and tools.

Postman

Public Postman collections wrap ReqRes endpoints for quick HTTP exploration and learning.

Hoppscotch

Frequently used as the default example endpoint in HTTP clients including Hoppscotch and Insomnia.

MSW (Mock Service Worker)

Often paired with MSW so frontend tests can intercept and stub ReqRes traffic deterministically.

Claude Code / AI Coding Agents

The /agent/v1/* sandbox is purpose-built for AI coding agents like Claude Code, with deliberate failure scenarios and cursor pagination.

Cypress / Playwright

Browser E2E test suites use ReqRes as a stable upstream when writing tests that depend on real network traffic.

Solutions 3

Packaged solutions this provider offers.

Self-Hosted Deployment

From $499/year per team, deploy ReqRes inside your own infrastructure with no external dependencies — useful for regulated environments that can't call a public service.

Scoped Per-Engineer API Keys

On the Team plan, issue scoped API keys per engineer with usage tracking, so a single project can attribute spend back to individuals.

Webhook Automations

On the Pro plan, configure webhooks that fire on collection data changes, letting ReqRes drive downstream pipelines as a prototyping backend.

  data:
  - name: Legacy Demo Fixtures
    description: Stable /api/users, /api/users/{id}, /api/unknown, /api/unknown/{id} fixture data preserved from the original
      reqres.in launch — the same payloads tutorials have been wired against for years.
  - name: Simulated Auth Flows
    description: /api/register, /api/login, and /api/logout return success-shaped tokens without creating real accounts —
      drop-in for teaching auth patterns without standing up a real identity provider.
  - name: Persistent Collections
    description: /api/collections/{slug}/records supports GET/POST/PUT/DELETE with real persistence on paid plans, with custom
      schemas on the Dev tier and above.
  - name: Project-Scoped App Users
    description: /app/* surface lets each app user authenticate independently with a session bearer, so client-side prototypes
      can model real per-user isolation.
  - name: Custom Endpoints
    description: /api/custom/{path} executes user-defined endpoints, letting builders shape arbitrary REST surfaces without
      writing backend code.
  - name: Agent Sandbox
    description: /agent/v1/* exposes endpoints designed for AI coding agents — cursor pagination, deeply nested resources,
      deliberate failure scenarios, and deterministic seeded fixtures.
  - name: 15 Deliberate Failure Scenarios
    description: The Agent Developer plan unlocks 15 failure scenarios on /agent/v1/scenarios so AI agents can be tested against
      timeouts, rate limits, validation errors, and pagination edge cases.
  - name: Delayed Responses
    description: Legacy endpoints accept a ?delay=N query param to simulate slow upstream conditions — useful for spinner/loading-state
      testing.
  - name: HTTPS Only
    description: Served exclusively over HTTPS at reqres.in.
  - name: CORS Enabled
    description: All origins are allowed, making ReqRes safe to call directly from browser-based prototypes.
- type: UseCases
  data:
  - name: Frontend Tutorial Endpoints
    description: The default fake API cited in React, Vue, Angular, and Svelte tutorials when an author needs a real HTTP
      endpoint without standing up a backend.
  - name: Bootcamp Curriculum
    description: Coding bootcamps wire exercises against ReqRes legacy endpoints so students can practice CRUD flows on a
      stable, free, no-signup surface.
  - name: API Client Test Suites
    description: Use the legacy and Collections surfaces to exercise HTTP client libraries (fetch, axios, requests, OkHttp)
      against a real REST API.
  - name: Frontend-First Prototyping
    description: Build a UI against persistent ReqRes collections before standing up a real backend; swap in a real API later
      by renaming the base URL.
  - name: AI Agent Testing
    description: Test AI coding agents against the /agent/v1/* sandbox — cursor pagination, deliberate failures, deterministic
      seeded fixtures.
  - name: Sales Demos
    description: Power live sales demos for tools that need to talk to an API without exposing customer data.
  - name: Workshop Sandboxes
    description: Hands-on workshops where every participant needs a working API endpoint in under a minute.
- type: Integrations
  data:
  - name: Postman
    description: Public Postman collections wrap ReqRes endpoints for quick HTTP exploration and learning.
  - name: Hoppscotch
    description: Frequently used as the default example endpoint in HTTP clients including Hoppscotch and Insomnia.
  - name: MSW (Mock Service Worker)
    description: Often paired with MSW so frontend tests can intercept and stub ReqRes traffic deterministically.
  - name: Claude Code / AI Coding Agents
    description: The /agent/v1/* sandbox is purpose-built for AI coding agents like Claude Code, with deliberate failure scenarios
      and cursor pagination.
  - name: Cypress / Playwright
    description: Browser E2E test suites use ReqRes as a stable upstream when writing tests that depend on real network traffic.
- type: Solutions
  data:
  - name: Self-Hosted Deployment
    description: From $499/year per team, deploy ReqRes inside your own infrastructure with no external dependencies — useful
      for regulated environments that can't call a public service.
  - name: Scoped Per-Engineer API Keys
    description: On the Team plan, issue scoped API keys per engineer with usage tracking, so a single project can attribute
      spend back to individuals.
  - name: Webhook Automations
    description: On the Pro plan, configure webhooks that fire on collection data changes, letting ReqRes drive downstream
      pipelines as a prototyping backend.
